CHARLES MORRILL, OF NEV YORK, N. Y.

FASTENER FOR THE MEETING-RAILS OF SASHES.

4SIIECIFIGATION forming part of Letters Patent No. 284,046, dated August28, 1883.

Application filed Julyn13, 1882. (No model.)

To all whom it may concern:

g Beit knownthat I, CnAnLEs MOREILL, of New York city, have inventedcertain new and useful Improvements in Sash-Locks, of which thefollowing is a specification.

My invention relates to that class of sashlocks in which the pivoted orswinging button or lock-bar on the upper sash is provided with aretractile bolt or catch to engage with the plate on the lower sash whenswung into engagement therewith, so as to prevent the un lockingmovement of the lock-bar, except by first releasing the catch from theinside of the house.

It also relates to those sash-loeks in which the lock-bar is pivoted ona horizontal axis and arranged to swing vertically up and down over thejoint of the meeting sashes.

My improvements aim to provide a sashlock of this type which,while beingvery secure,willbe simple in construction and less view of my improvedsash-lock shown in itsl expensive to manufacture than Vthose heretofore;and my improvement chiefly relates to the manner of producing theretractile catch or burglar-proof engagement between the lockbar and thehook or plate on the lower sash; and this may be stated to consist inpivoting the lock-bar to a lug which has a hinged or pivoted connectionto the baseplate on the upper sasl1,with a spring to constantly pullsaid lug down upon the base, whereby the lockbar is allowed to spring oryield forward when swung down into its locking position, and thus permita latch-tooth on thelock-bar to ride over and snap into engagement witha hook or latch on the lower sash, which thereby locks the two insecureburglar-proof engagement.

. Myinvention also consists in details of construction relating to thelatching or locking teeth, and also to the hinging-lug and lockbar,whereby the lock-bar is held firmly in its upright or unlocked positionwhen so placed, to prevent the lock -bar from falling over against the.raised sash, as hereinafter fully set forth.

In the annexed drawings, Figure 1 is a plan locked position. Fig. 2 is asectional end elevation shown in the unlocked position. Fig.

3 is a front elevation in the same position. Figa is a sectional frontelevation of the parts affixed to the upper sash. Fig. 5 is a plan viewof the hinging-lug removed; Fig. 6, a vertical section thereof on m;Fig. 7, a perspective view of the same.

In Figs. l, 2, 3, and 4, b indicates the top bar of the lower sash, anda the bottom bar of the upper sash.

d indicates the base-plate of that part of the sash-lock which isaffixed to the lower sash, and c the base-plate of the part affixed tothe upper sash.

c indicates the lock-bar, button, or lever of the sash-lock, which baris mounted on the base-plate c of the upper sash, and is pivoted on ahorizontal axis-pin, f, so as to swing verA tcally Clown over themeeting joint of the sashes upon the base-plate d oi" the lower sash, asshown by full lines in Fig. 1 and indicated by dotted lines in Fig. 2.The lock-bar is not pivoted directly to the base-plate, but to ahinging-lug, g, which has a'hinged or pivoted connection with thebase-plate, as `will hereinafter appear, and the pivotal end of thelock-bar is forked or cleft, as seen best in Figs. l, 3, and 4, tostraddle the lug, as shown, and the base ofthe cleft is indented ornotched to form a latehing shoulder or lock tooth, h, which, when thelock-bar is swung down into its locking position, will engage with anarrow-head or latching-hook, t', projecting from the base-plate d of thelower sash, in coincidence with the cleft in the pivoted end of the bar,as will be readily understood from Figs. l, 2, and 3. Now, thehinging-lug g is formed with a base-flange, lc, to rest on thebase-plate c, and with an underlying central tongue, Z, which passesthrough a slot across the middle of the base-plate (see Figs. 2 and 4)and projects within thehollow of the baseplate, as shown. Through thefrontend of the tongue Z is passed a pin, m, which underlies thebase-plate, and the front edge of the baseiiange 7c, above thebase-plate, is rounded off, as best shown in Figs. 2 and 7. Thelug g hashence a pivotal or hinged connection with the baseplate, and while it isprevented from becoming bodily raised up or detached from the base bymeans of the pin an, it can yet rock slightly forward or backward on therounded edge lc', as will be understood. The back end of the tongue isperforated with a short slot, through roo Y which is passed a bow orleaf spring, ,whose ends bear on the under side of the hollow baseplatec, and thus constantly 'tend to hold the hinging-lug in its quiescentposition, ywith its 5 base-flange k seated firmly on the base-plate c,

as shown in Figs. 1, 2, 4, and 6.

` Referring now to Fig. 2, it will be seen that if the lock-bar e beswung down while the hinging-lug vis in its quiescent position, the arcthrough which the lock -tooth h moves will intersect the inclined .faceof the latchhook z', and the two will thus come into opposing contact.If, however, the lock bar be pressed firmly downward, or if it be pulledslightly forward, the hinging-lug g will yield forward slightly, andthus permit the lock-tooth h to ride easily over the inclined face ofthe hook i till the hook arrives at the barb or engagingnotch ofthehook, when the two will then spring into secure engagement by thereaction of the spring n on the hinged lug g, as will be readilyunderstood, thereby causing the two parts of the sash-lock to become soengaged that they cannot become burglariously unlocked by any implementsinserted between the sashes. When, however, the inmates ofthe housedesire to unlock the sashes, this can be readily done by first pullingthe lock-bar e forward slightly andthen raising it upinto the positionshown ily moved up or down.

It will be noted on reference to Figs. 1,2, 3,

and 4 that the tip of the latch-hook i is tapered or beveled, so thatVit will readily enter the slot of the lock-bar e when the latter isswung down into its locking position, although the hook and the slot maybe slightly out of line with each other.

If desired, the sides of the slot may be tapered, instead ofthe top orsides of the latchhook, with equivalent effect, as will be understood,and it will be readily seen that by this means not only will thelock-bar engage with the hook easily, even if out of line, but in thusengaging with the hook it will at the same time bring the two parts ofthe sash-lock and the two sashes into theirtrue central or relativepositions, which is a very desirable lfeature in the operation of thelock.

Now, a minor feature of my invention consists in means to hold thelock-bar in its raised position, as seen in Fig. 2, when thus placed, soas to prevent its falling over against the Alower sash, and thusbecoming jammed between the sashes.

Referring to Figs. 2, 5, 6, and 7, it will be seen that slots o o areformed through the baseange la of the hinging-lug g close on either sideof the lug, which slots admit the tines or branches of the forkedpivotal end of the lockbar e, as seen in Figs. 2 and 4. Now, the frontand lower corner of these tines is rounded off to a circular curvestruck from the pivot center f and tangent to the surface of the base c,

(see Fig. 2,) while the remainder of the end of the tines is tangent tosaid circle and coincident in Fig. 2, when both sashes may then bereadto the surface of the base. It will hence be readily seen that therounded concentric corner on the' pivotal end of the lock-bar will allowthe rock-barato swing down freely into its locked positionwhen soforced; but when swung into its raised position, as seen in Fig. 2, theiiat or tangent end of the lock-bar will coincide with the nat surfaceof the base, and will be held close thereto by the retraction of thehinging-lug g, thus holding the lock-bar firmly in its upright position,somewhat similar to the manner in which the blade of is -held whenopened.

It will be noted of course that the tangent end of the lock-bar shouldnot be exactly at right angles to the upright sides of the bar, but at aslight inclination, so as to allow the lock-bar to inclinev backwardwhen raised, and thus bring the center of gravity of the lockbar on thatside of the axis on which the spring n acts to hold it, as will beunderstood.4

It will be noted that. knobs r r, of ornate pyramidal shape, are fixedon each end of the pivot-pinf and project from each side of thelock-bar, and thus impart an attractive ornamental iinish to the bar 5and it will be also noted that the bar in front or plan view is designedin an ornamental cruciform shape, which greatly improves the appearanceof the sash-lock. 'Ihese ornamental qualities of the construction ordesign I reserve, however, for the subject of a design patent.

As shown best in Fig. 2, I prefer to form the hook i separate from thebase-plate a, but with a shank, which is inserted in a slot in the base,and there rigidly held by riveting the end of a pocket-knife roo theshank, or by the pins s, as illustrated. I t

will therefore be readily noted that by the construction described bothbase-plates c d are formed separately from their attachments and withoutany protuberances, so that the surface of the base-plates,-when cast,may be nished off smooth and bright, and the attachments i g afterwardVaffixed thereto, which will be less expensive in the manufacture andallow a better finish.

Any other equivalent and elastic or for- IIO wardly-yielding connectionof the lock-bar e with the base-plate besides that shown may be adopted,and any other form of engaging latch-teeth h z' may be substituted forthose shown without departing from the principle of theinvention.

Any novel feature which I may have shown but not claimed in thisapplication I reserve for the subject of a future application.

W/hat I here claim as my invention is= l. In asash-lock, thecombination, with a lock-bar arranged to swing over the joint of themeeting sashes, of a forwardly-yielding lug to which the lock-bar ispivoted, and which is hinged to one sash, with a projecting hook affixedto the other sash, and an `engaging latch hook or shoulder on thelock-bar to engage therewith, substantially as and for the purpose setforth.
